The Steering Committee sets priorities for the strategic direction of GPML, including its further development, its relationship with other initiatives, its priorities and structure; identifies activities for GPML through annual work plans and evaluates its progress in that regard; and promotes GPML action and initiatives and its benefits as a multi-stakeholder partnership. The current co-chairs of the Steering Committee are Fredrik Haag (International Maritime Organization) and Sarah Da Silva (Environment and Climate Change Canada).
Any GPML member can propose a new Steering Committee member. The Secretariat approves new members in consultation with the Steering Committee. Consideration is given to limiting the number of members in order to ensure adequate and effective communication. Steering Committee membership is subject to rotation while ensuring continuity of membership.
